UNITED STATES PATENT OFFICE.

GEORGE FQAIHL'ERS, or coviNG'roN, KENTUCKY.

CATTLE FOOD AND PROCESS OF MAKING SAME- ington, in the county of Kenton andState of Kentucky, have invented certain new and useful Improvements in Cattle Feeds and Processes of Making the Same; and I hereby declare the following to be a full, clear, and

exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to cattle feeds and processes of making the same; and consists in .a cattle feed comprising a mixture of cooked and partially digested crude natural feeds with components of distillery slop and'also in a-method of pre aring such feed com rising the steps-of cooking and chemically a tering crude natural feeds by the action of hot distillery slop and. thereafter reparing a feeding material from such coo ed and altered feeds and the distillery slop; all as more fully hereinafter set forth and as claimed.

In a prior patent No. 821,326, May 22, 1906, I have described and claimed a process of making cattle feed from distillery slop and the product of the same, such process consisting in separating distillery slop into liquid and solid portions, rendering the latter granular and absorbent, reducing the liquid to a syrup and incorporating the same interiorly into the absorbent granules and finally drying the whole. The finished roduct substantially represents the whole 0 the original grain used by the distiller, save only the starch which has been converted into alcohol and removed, and is therefore a concen-. trated feed, very rich in proteid matter and,

proteid matter having a relatively high maret value, is valuable enough to be able to stand transportation for long distances to points of consumption. In use for feeding cattle however it is customarily employed in connection with more or less carbohydratematter equivalent to the starch which the distiller has removed, or to a portion of such starch, and forms a useful component of bal anced rations or a su plement to ordinary, less nitrogenous feeds. i tarch however also being relatively expensive, it is the purpose of the present invention to replace it, at least in part, with cheaper carbohydrates and to produce a feed com rising in addition to the richproteid af't'or ed by the slop, aportion of carbohydrate matter, doing this by a Specification tr Letters Patent.

simple, cheap and ready method giving a commercially valuable product, and, incipractice of the process. .1

In coarse natural fibrous feeds of many kinds, and particularly in those, commonly called roughage. by the farmer, thereare valuable butwh ch, are, as occurring in such feeds, actually relatively little available, causing such rough feeds to be usually regarded as, in away, more diluents; bulkgiving feeds to be used with grain, bran and like rich feeds. As to the nature of these carbohydrates, relatively little is known, but many are pentosans, such as araban and xylan, and some are hexosans. In the form have discovered that by cooking these roughhydrolysis, much increasing theinavailability as' cattle feeds, and the contained carbohydrates are .much more digestible by cattle, the acidity and chemical action of the slop no doubthaving much influencein this regard. Ground corn cobs, straw, hay, comminuted corn stalks and many kinds of roughage show this phenomenon, and when so cooked yield large amounts of carbohystarch of the grain in the com lete feed. Slop issues from the still at a hig l tempera.- ture and is generally quite acid, though the degree of acidity of course varies, and by introducing the roughage into such slo at once, the desired cooking and partial dige stion take lace before the slop cools much below the oiling point. The true celluloses forming part of the roughage are probably not much altered or changed by this cooking luloses are more susceptible and, together with other carbohydrates, yi d digestible products. If necessary, the 'ixture of slop androughage may be stored for atime under circumstancesreducing loss-of heat, for mutual interaction. Heat may also be supplied to the. mixture from an external source,

rou hag e in the slop, separating the liquid and soli portions of the mixture after such cookdentally, gaining many advantages in the in which they occur in these feeds, these, bodies do not seem readily digestible. I

many carbohydrates wh ch are intrinsically age feeds in fresh hot distillery slop in the condition in which it leaves the still, they undergo a sort of partial digestion orpartial drates serving to replace the abstracted operation,but the less definite,'hydrated celut this is not ordinarily necessary. -It'i s found. that by so ,cooking a vproportion of ing, rendering. the latter absorbent, reducing addition to the rich proteids of the slop available carbohydrates from such roughage.

' tions with the s u y solution of the Of course where very rich nitrogenous feeds are desired, as 'in such as are to be ship ed long distances, or are intended to be used on the farm to heighten the richness of grain and other feeds less rich than desiccated slop, it is substantially undesirable to add foreign matter to the distillery slop, and it is better to rely upon the insoluble solids ofthe slop itself for absorption of the soluble solids, as

in the manner described in the aforesaid patent.- In many slops the former are in any case sufficient for convenient and advantageous working, and in all they may be made suflicient by a series of successive impregnasoluble solids, as descri e in said patent. But in many slops, and in articular in those from rye mashes, the inso uble solids are not large in amount and are somewhat disadvantaeous in hysical characteristics, rye slop eing rather glutinous" and containin much of its suspended matter in the form 0 very fine particles, tending to run through screens, and coarse and rapid filtering devices. With such slo s where, as in the present invention, a fee is, desired not quite so rich in proteids and containin more carbohydrates, the use of the state roughage bodies offers many advantages in the process of desiccating. On adding a modicum of comminuted roughage, corn cob meal being very suitable, to the hot slop as it issues from the still, the roughage is cooked and partially digested, as stated, renderin its contained carbohydrates more availab e. The rou hage is. softened, cooked and in part, no dou t, is dissolved, the dissolved constituents going to join the soluble constituents of the slop. Simultaneously, the slop itself is more or less clarified, fine floating matter being entangled 'or held by thefibers, so that se aration-mto liquid and solid portions is muc facilitated,

In separating the cooked mixture into liquid and solid portions, the relatively harsh fibrous matter of the cob meal or other roughage, serves as a backing or holder for the softer, frequently rather slimy, solids of the slop, permittin good and rapid separation by screens, filter presses, centrifugals or other a .paratus. presence 0 the roughage proves ver desirable as forming, in away, a sort of ltering layer or lining in the filter press, through which the liquid portions run, giving a pellucid filtrate very desirable in the subsequent evaporation in multiple effects and the like. Through such a layer derived from cooked In a filter press, the

roughage and slop, plain slop maybe run to gain clear filtrates. Most slops contain considerable very finely divided matter which embarrasses the operation of evaporating apparatus and sometimes does not allow reduction to be carried as far as is desirable. But in slops cooked with roughage or in slops filtered through deposits from such roughage slop mixtures, this fine matter is not found in the separated liquid, even where relatively rapid, coarse filtering a paratus is employed. Rye slops yield good fi trates in this manner of operation.

In the subsequent incorporation of the syrup formed from the filtered liquid into the absorbent solids, the presence of the fibrous roughage among the latter is very desirable as it adds to the volume of absorbent and is itself very absorbent. With admixed coinminuted cooked roughage and slop solids, the syrup is very thoroughly absorbed, relatively little being left exteriorily of the lgranules, and the impregnated mass may be ;rapidly dried in any convenient drier without fear of sticking or burning. Usually the absorption and im regnation may be performed in one stage, t iough if little roughage be used or the syrup reduction be not carried far, it is sometimes desirable to perform it in several stages, drying between to restore absorptive power. I

The resultant'product of the complete process is a dry, granular feed comprising the insoluble solids of the slop employed admixed with the insoluble portion of the roughage remaining after the cooking operation. Interiorly incorporated in the granules are the soluble solids of the slop and the matter dissolved by the solvent action of the slop upon the roughage in the initial cooking. Ordinarily, it is a light yellow to dark brown granular mass, the color depending somewhat u on the particular method of drying ado ted With a mixture of one-third cob me'a and two-thirds rye-slop, solids, carried through the described process and finally dried in a hot air drier, it has somethin the color and appearance of ground, roasted onifee. On mastication, the granules taste initially rather sweetish, from dextrinization and caramelization in dryin and finally sourish where sour mash slo has been emloyed, the contained solub es coming out 1n such mastication. Cattle eat the new feed greedily. As the process enables the reduction of the hot slop to the dry feed to be carried out continuously and rapidly, there is no pause during which fermentation and formation of disagreeably smelling and tasting higher fatty acids, such as butyric, can occur. The contained acid of the'interiorly incorporated slop solubles is mostly lactic acid which has a asantly sour taste without disagreeable af ter taste and which develop the original taste of t e slop, being ice ' then preferably separate the liquid from the solid portions by any suitable means, render the insoluble solids absorbent by heat or" pressure,reduce the liquid to a syrup, absorb this syrup in the granulated absorbent solids and dry. Impregnation and dryingmay be performed in several stagesif desired. Drying may be done in any of the ordinary commercial apparatus sold for that purpose. Rotary d'riers are perfectly suitable since the sticky slop solubles being interiorly incorporated in the granules, the granular mass does not stick to the 'walls or clump together.

-My new feed inits preferred form consists of a dry granular mass comprising particles of cooked, partially predigested comminuted roughage admixed with the insolubles of dis tillery slop, with the solubles of said slop and the digested solubles of the roughage interiorly incorporated therein; said feed being ordinarily light yellow to dark brown, having a pleasant odor of roasted grain, and tasting at first sweet and caramel-like and subsequently tasting more like the original slop, while devoid of any un leasant, rancid or spoiled flavor or taste. t may of course be admixed with bran and other cattle foods in any desired. proportionin making complete rations.

The cooked, partially digested roughage and slop may be fed to cattle direct without drying, but such use is not ordinarily so advantageous, particularly where the liquid is simply screened out and rejected, as this liquid contains much of the values.
